A 6 year research lead by Dr. David Llewellyn and his team at the University of Exeter Medical School, concluded that low levels of vitamin D in older people are linked to the risk of developing dementia. Vitamin D can be found in foods, such as oily fish, supplements, or exposure to sunlight, however elderly people have less efficient skin and must be supplement in other ways. The team found that in 1,169 subjects with sufficient levels of vitamin D, there is a 1 in 10 chance of developing dementia. In 70 subjects with deficiency, there was a 1 in 5 risk of getting dementia. They cannot say that low vitamin D causes dementia but it is worthwhile to continue studying the connection. What are your thoughts on the association of dementia risk with low vitamin D?
